There are so many things, but I see this as a two part answer regarding the surprising elements of the entrepreneurial journey. The first is that failures truly are a rite of passage for future successes and bigger wins. I’ve had a lot of wins and also failures, but the failures have generally taught me more about how to succeed than the wins have. Of course, some entrepreneurs get lucky and win right away but that seems to be a rare occurrence. Second, don’t underestimate the power of perseverance. In a startup, you can sometimes feel like everything is going wrong and there isn’t a light at the end of the tunnel, but if you just stay on course (through the pain), you can sometimes get to a point where the acceleration just kicks in and takes your business to a level you didn’t think would be possible.
